Choose the configuration for your installation and include the required region, interfaces and quantity in your enquiry.
Request a quote for this modelMinimum local setup
- A Windows PC with RTCU M2M Studio.
- The device, its documented power source and model-specific programming cable. Install the driver required for that connection.
- Antennas for the radio interfaces you use; a SIM and service subscription if the application uses cellular connectivity.
Remote M2M Studio access adds network connectivity and the RTCU Communication Hub. The Deployment Server is optional for managed remote updates.
